Answer:
Here Bub. (Nice PfP) I got aproximently 16 (15.924).
Step-by-step explanation:
The formula for Circumference if I remeeber right is pi times diameter. Now we can flip the equation to Circumference divided by pi. If pi is the standard pounding of 3.14, you will get 15.9235, almost 16
First, solve for each of the angles. Since it is a right triangle, one of the angles is 90 degrees. Knowing that the sum of the angles of a triangle are always equal to 180 degrees, you can write an equation for the triangle.
Angle1+ angle2+angle3=180.
Which means that 90+(x+15)+2x=180.
After finding the value of x, which is 25 in this case, solve for each angle.
X+15=25+15=40.
2x=25*2= 50
The value of the smallest angle is 40 degrees.
Answer:
3 seconds
Step-by-step explanation:
16 = 160 - 16t²
16t² = 144
t² = 9
t = 3

Pi/3 is in the first quadrant, and all trigonometric functions are positive in the first quadrant,
Therefore, cos pi/3 is positive.
